Hi Wubie
To calculate the energy consumption of cryptographic and steganographic processes, you need to measure the computational resources used during these operations, such as CPU time and power consumption.
Here’s a general approach to achieve this:
1. Profile the Code: Use MATLAB's "tic" and "toc" functions to measure the execution time of your encryption, decryption, hiding, and extraction processes.
2. Estimate Power Consumption: Determine the average power consumption of your CPU, which can be obtained from system specifications or external tools.
3. Calculate Energy Consumption: Use the formula Energy = Power × Time to calculate the energy consumption for each process in joules.
Below is an example implementation:
% Define the encryption, decryption, hiding, and extraction functions
function encryptedData = encrypt(data)
% Example encryption algorithm
encryptedData = data; % Replace with actual encryption logic
end
function decryptedData = decrypt(encryptedData)
% Example decryption algorithm
decryptedData = encryptedData; % Replace with actual decryption logic
end
function stegoData = hideData(data, message)
% Example data hiding algorithm
stegoData = data; % Replace with actual steganography logic
end
function extractedMessage = extractData(stegoData)
% Example data extraction algorithm
extractedMessage = ''; % Replace with actual extraction logic
end
% Sample data
data = 'This is a sample data';
message = 'Secret';
% Measure encryption time
tic;
encryptedData = encrypt(data);
encryptionTime = toc;
% Measure decryption time
tic;
decryptedData = decrypt(encryptedData);
decryptionTime = toc;
% Measure hiding time
tic;
stegoData = hideData(data, message);
hidingTime = toc;
% Measure extraction time
tic;
extractedMessage = extractData(stegoData);
extractionTime = toc;
% Assume average power consumption (in watts)
averagePower = 50; % Replace with actual power consumption of your system
% Calculate energy consumption (in joules)
encryptionEnergy = averagePower * encryptionTime;
decryptionEnergy = averagePower * decryptionTime;
hidingEnergy = averagePower * hidingTime;
extractionEnergy = averagePower * extractionTime;
% Display results
fprintf('Encryption Energy: %.4f J\n', encryptionEnergy);
fprintf('Decryption Energy: %.4f J\n', decryptionEnergy);
fprintf('Hiding Energy: %.4f J\n', hidingEnergy);
fprintf('Extraction Energy: %.4f J\n', extractionEnergy);
Hope this helps!
